Veilbreak is a powerful, illegal street drug, known for inducing a dreamlike euphoria in those who partake of it. For a rare few, it instead allows sight beyond sight, revealing the invisible monsters that feed on the souls of the innocent. You are Veilbroken, gifted or cursed with this ability. It's up to you to seek out the source of these creatures and destroy it for good. But does the answer lie in the world of dreams, or somewhere much more mundane?

The Veilbreak Delusion is an open-ended, setting-agnostic campaign modifier that can be dropped into any game as a main or side element. It features rules for using Veilbreak and 19 new adversaries, each based on one of my own hallucinations.
